Test Procedure
The test involves sending sample VLAN packets to a test target NIC card and
verifying that the packets are not discarded by the pre-processing step, but are
passed on to the TCP/IP stack on the operating system at the computer hosting the
NIC card.
verifying that the packets are not discarded by the pre-processing step, but are
passed on to the TCP/IP stack on the operating system at the computer hosting the
NIC card.
The test requires a configuration as shown in the following diagram.
The test target NIC is connected to one port of a simple hub. The hub is connected to
the network backbone or subnet. You also need a packet generator host capable of
generating Ethernet traffic. The packet generator host will be connected to another
port on the hub.

The packet generator host equipment can be either a dedicated packet analyzer or a
computer with a software-based packet analyzer capable of generating Ethernet
traffic.

There are a number of software packet analyzers available that can be used for this
purpose. For a comprehensive list of reliable analyzers, visit the Cooperative
